摘要
台湾海峡内各种与潮波相关的现象,可以归因于在地形及岸线的影响下自台湾海峡南北两端进入的潮波的相互作用。近20余年来台湾海峡潮波的研究获得显著进展,然而即使作为台湾海峡主要分潮的M2分潮,其相关研究中也还存在着诸多分歧。从台湾海峡M2分潮潮波分布特征及解释研究出发,并针对以往各种研究中差别较大的M2分潮潮流的分布及变化特征,归纳总结了相关研究的主要分歧:(1)对台湾海峡M2分潮潮波的研究的争议主要集中在2点,包括对自台湾海峡南、北两端进入海峡的潮波的作用范围的研究以及台湾海峡内部潮波系统形成机制的探讨;(2)台湾海峡M2分潮潮位分布研究的主要分歧在于对台湾岛西岸潮时潮差的分布特征的解释;(3)台湾海峡M2分潮潮流研究中最大的差异在于对最大潮流同潮时线分布特征的描述,其实质仍为对潮波作用范围的描述;对应于M2分潮最大潮流同潮时线研究观点的差异,在M2分潮圆流点是否存在、圆流点存在位置及圆流点旋转方向的研究上也存在着较大的差异;对台湾海峡内部椭圆率为零的分隔线位置的讨论,主要分歧在于该椭率零线靠近台湾岛附近及澎湖列岛附近时的分布状况。此外,最强流区的位置判定及极值区潮流流速量值的大小问题上也存在差异。
Phenomena relating to the tidal wave in the Taiwan Strait can be attributed to the interaction between the tidal waves coming from the north and south entrances of the Taiwan Strait under the influence of topography and coastline. Although significant progress in the studies on tidal waves in the Taiwan Strait has been made in the past 20 years, there are still many differences in the relevant studies. In this paper, staring from the studies on characterisitcs and interpretation of the M_2 tidal wave distributions in the Taiwan Strait and aiming at the differences in relevant studies on the M_2 tidal current distributions and variations, the main differences in relevant studies are summarized as follows: (1) the main controversies over the M_2 tidal wave in the Taiwan Strait are concentrated on two aspects, one is the action ranges of the tidal waves coming from the two entrances of the Taiwan Strait, and the other is the formation mechanison of tidal wave system in the Taiwan Strait; 2 the main controversies over the M_2 tidal level distributions are the interpretations of the tidal phase and range distribution characteristics along the west coast of Taiwan Island; 3the great differences in the M_2 tidal current studies are the description of cotidal lines of maximum tidal current, including the controversies over the existence, location and rotational direction of the M_2 tidal current amphidromic point and the location of the separation line with ellipticity being equal to zero in the Taiwan Strait. In addition, there are also the controversies over the location of the maximum tidal current area and the magnitude of tidal current speeds in the extremum area.
